| 摘 要： | In this letter, the sensitivity of an uplink Multi-Tone Code-Division Multiple Access （MT-CDMA） system to the Carrier Frequency Offset （CFO） is investigated. The analytical expression for the Bit Error Rate （BER） of uplink MT-CDMA in the presence of CFO is derived in a multipath Rayleigh fading channel which is verified through simulations. Both Maximal Ratio Combining （MRC） and Equal Gain Combining （EGC） are considered in combining multipath signals in the analysis. It is found that the BER performance can be improved with the number of multipath increasing in the presence of CFO.
